[In Vitro]

(Leu31,Pro34)-Peptide YY 在大鼠额顶叶皮质膜制剂 (Y1 富集组织) 和兔大隐静脉 (Y1 体外生物测定) 中表现出高亲和力 (nM)，但在 Y2 富集制剂 (大鼠海马) 中仅表现出低亲和力[1]。

[In Vivo]

(Leu31,Pro34)-Peptide YY (0.1-1 nmol/day; ICV; 14 days) 对大鼠有抗焦虑和抗抑郁作用[2]。 Animal Model: Male Sprague Dawley rats weighing 150-170 g, OBX/Sham model[2] Dosage: 0.1, 0.3 and 1 nmol/day Administration: ICV, for 14 days Result: Significantly decreased hyperlocomotion and immobility time in OBX animals. Reversed the deficit in social contacts in OBX animals. Reduced grooming behavior in sham animals.
